APIARATUS FOR GENERATING OB PRODUCING GAS.

at 1 London Wall Buildings, London Wall, 5

London, in the county of Middlesexylfilng land, have invented certainnew and useful Improvements in Apparatus for Generating or ProducingGas, of which the following is a specification.

This invention relates to certain improvements in apparatus forgenerating or producing gas and refers more particularly to an apparatusfor feeding or distributing fuel to a generator or producer of suctiongas plants used in conjunction with gas 'engines or internal combustionmotors.

This invention is also applicable to generators or producers forgenerating gas for gas fired furnaces, boilers and the like, and to anypurpose when combustible gas is required.

This invention refers more especially to certain improvements in thegenerator or producer which is the subject of a joint application ofmyself and "William Jordan, Serial No. 800,965, filed November 14, 1913.

The object of this invention is to provide a suitable feed hoppermounted on the top of the generatingchamber adapted to feed large logsof wood or such like fuel to the generator, being adapted for use incombination with a basket like chute removably fitted therein whichenables wood shavings, sawdust and such like fuel to be fed to thegenerator in such manner that the said fuel will not pack as is thecasev with generators as at present constructed. Means for the admissionof air to the generator are provided in such manner that the fuel isconsumed from the bottom and the fire prevented from reaching the top ofthe feed hopper. T accomplish this object by providing a superimposedfeed hopper mounted above the generating'chamber having a feed openingat its top fitted with a removable cover to enable fuel to be fed to thegenerator. Within this feed hopper is arranged a removable basket likechute to enable sawdust, shavings, fine coal or the like fuel to be fedto the generator without packing and at the same time enable the saidfuel to gradually deliver to the incandescent fuel in the generator.Means are also pro- Specification of Letters Patent.

vided for the admission of'air and superheated steam to the generatorbelow the basket like chute to assist combustion.

This invention will'now be more fully desc'rlbed aided by a reference tothe accompanylng sheet of drawings in which- 1F lgure 1 is a verticalsection of the top portion of a gas-generator showing the basket likechutemountedtherein for feedlng sawdust, shavings, fine coal or the likefuel to the generator while Fig. 2 is a some what similar view of thetop portion of a gas generator with the basket like chute removed toenable large logs of wood or the like to be fed to the generator. beunderstood that the other portions of the generator may be of knownconstructions more especially as shown and described in the priorapplication No. 800,965, previouslyreferred to;

According tothis invention 1 provide a superimposed stoking chamber -1for large fuel mounted on the top of the generating chamber 2 and whichcomprises a steel shell 3- preferably lined with fire brick =1 having afeed opening 5 at its top fitted with a removable cover 6 through whichopening fuel is fed to the generator chamber '2. When shavings, sawdust,fine coal or the like is to be used as fuel for the generator, asupplementary stoker in the form of a suitable cylindrical and somewhatbell mouthed basket like chute 7 is inserted in is connected to a funnelshaped hopper or the like 9 which is furnished with a flange It will orring 10 adapted to bear on the flange-of the feed opening 5 at the topof the stoking chamber 1 and held in position thereon by a suitablejoint ring 11 arranged between the aforesaid flange or ring 10 and thedoor or cover 6, thus the basket like chute and the hopper portion canbe readily and bodilv removed when different fuel such as logs of woodor the like is to be fed to the generator chamber 2.

In operation, when shavings, sawdust, fine coal or the like fuel is tobe used for the generation of gas the fire therein is allowed to reachto about the top of the mass ,thereof when the basket like chute isfilled :with fuel until it spreads about the top of the incandescentfuel in the generator as shown. The apparatus is operated by. a downdraft from the engine through the generating chamber 2 in an ordinarymanner. The zone of combustion rises in the perforated or woven wireportion 8 of the basket, the openings therein permitting free passage ofair through the fuel therein causing the same to be consumed from the abottom in a similar manner to a solid piece of fuel such as a log ofWood, by being gradually charred at the bottomthe closed in top portion7 of the basket like chute preventing combustion of the fuel above thetopof the perforated portion 8. Means are also provided for theadmission of superheated steam to the top portion of the generatorchamber 9 below the basket like chute. For this purpose an annularohamber 12 formed about the feed hopper 1 as shown in Fig. 1 is providedconnected by the pipe'13 toa flash vaporizer or other above theincandescent fuel when by the admission of air and superheated steam asbefore stated, the bottom ends of the logs become gradually charred whenthey fall .over on their sides and become totally consumed.

What I claim and desire to secure by Letters Patent of the United Statesis An apparatus for generating gas comprising a generating chamber, astoking chamber mounted thereon and having a feed opening in its topadapted to receive logs or other large fuel, and a detachable chute forshar ing's and other small fuel suspended fromsaid opening Within saidstoking chamber, said chute being tapered from its top downward towardits center and thence flared outward to its bottom, the upper portion ofsaid flared section being solid and the lower portion thereof havingopenings in its Walls.

In testimony whereof I afiix my signature in presence of two Witnesses.
